Meet Ro-bat, Brown University's Robotic Bat Wing

submitted by: nsf
The strong, flapping flight of bats offers great possibilities for the design of small aircraft, among many other applications. By building a robotic bat wing, Brown University researchers have uncovered flight secrets of real bats. Bat wing project leader and NSF Graduate Research Fellow Joseph Bahlman says the faux flapper generates data that could never be collected directly from live animals, and may lead to improved aircraft efficiency and help in the design of small flapping aircraft.

Science Nation - Purple Marsh Crabs

submitted by: nsf
If you take a quick glance at the marsh next to Saquatucket Harbor in Harwich Port, Massachusetts, you will notice right away that some of the grass is missing. The cordgrass there, and all around Cape Cod, has been slowly disappearing for decades. "The cordgrass that's being destroyed here is the foundation species that builds salt marshes," explains marine ecologist Mark Bertness of Brown University. With support from the National Science Foundation, Bertness studies this critical...

Science Nation - Batty for Bats

submitted by: nsf
These creatures of the night could be the models for future aircraft! "If you just watch them in the sky, they can fly like nothing else. A bat can make a 180 degree turn at full tilt in three wing beats and go back the other way ... it's a pretty amazing creature." ~ Kenny Breuer, Brown University For more Science Nation, go to http://www.nsf.gov/news/special_reports/science_nation/index.jsp
